CUTTING MECHANISM FOR ClGAR-WRAPPERS.

SPECIFICATION formingpart of Letters Patent No. 723,947; dated March 31, 1903.

I Application filed August 30, 1902. Serial No. 121,568. (No model.)

T on whom it may concern.-

Be it known that LOLUF TYBERG,a.citizen of the United States, residing at New York city county of New York, andState of New York,

have invented certain new and useful Improvements in Cutting Mechanisms for Cigar- Wrappers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

IO The invention relates especially to mechanisms for cutting cigar wrappers or binders.

In cigar-wrapper-cutting mechanisms of the class having a cutting-die over which the leaf is laid and a codperati'ng rollerv adapted to reciprocate over the die difficulty has been experienced heretofore in obtaining a proper coaction between all parts of the cutting edge of the die and the roller. Various devices have heretofore been employed for overcomzo ing this difficulty. The present invention aims to avoid this J difficulty by providing means for shifting thedie, so as to cause the roller to cooperate with a portion of its cutting edge on one stroke of its reciprocation and with the remainder of the cutting edge on its return stroke. The roller will thus coact with only one cutting edge at a time, and all difficulty due to obtaining a proper coaction between the roller and the cutting edges is avoided.

A full understanding of the invention can best be given by a detailed description of a construction embodying the various features thereof in the preferred form, and such a de- 5 scription will now be given in connection- With the accompanying drawings, showing such a preferred construction. I

In said drawings, Figure'l is a side view, partly in section, of a hand-machine constructed in accordance with my invention; Figs. 2 and 3 are detail views showing the cutting die and roller. indifferent positions. Fig. 4 is a bottom plan view.

Referring to the drawings, 10 represents a screws 14. The cutting-die 11 is formed by a knifehaving a general elliptical form, but modified from atrue ellipse to cut a wrapper of the usual or any desired form. The knife is mountedon a support 15, which normally rests by means of lugs 16 on rock-shafts 17 and 18,,which are mounted in hangers 19, depending from the under side of the table 10. The lugs 16 carry upwardly-extending brack- 6o ets 20, wbichcarry cam-studs 21 in position to be engaged by cams 22 and 23 on the rockshafts 17 and 18, respectively. These cams 22 and 23 are formed so that when in normal position the lugs '16 are permitted to rest on the rock-shafts, and the die will then be in position with its cutting edge preferably substantially flush with the surface of the table, as shown in Fig. 1.

By rocking the shafts 17 and 18 the cams 7o 22 and 23 may be moved to carry their raised portions beneath the cam-studs on brackets 20, thereby raising one or the otherof the edges of the die-support 15, according to which of the sets of cams has been moved into operative position, and thereby tilting the support and the die,.asshowninFigs.2and3. Thecamsareso formed and the rock-shafts so connected that when cams 22 are moved into posit-ion to raise one side of the die-support the cams 23 will be 8o inoperative, and vice versa. As shown, the cams 22 and 23 have their raised portions on opposite sides,and the rockshafts are connected by means of a link 25, connecting dependingarmson the shafts. The shafts are rocked by means of connections with the pivoted arm 13. For this purpose an oscillating yoke 26 is provided, pivotally supported beneath the table and connected by means of a link 27- With an arm on the shaft 17. the yoke 26 the arm 13 carries a short arm 28 beneath the table, provided with a stud 29, adapted to engage shoulders 30 and 31, respectively, on the yoke when the arm is at or near the extremities of its oscillating movements, and thereby slightly shift the yoke. By this construction when the arm is moved from its normal position, as shown in Fig. 1, the yoke will be thrown by engagement ofcthe stud 29 with the shoulder 30 to rock the shafts Ioo and cams to the position shown in Fig. 2, thereby raising the inner edge of the die into For oscillating oposition to coact with the roller as it moves thereover. The die will remain in this position during this reciprocation of the roller and until the stud 29 comes into engagement with the shoulder 31, whereupon the yoke will be thrown to the position shown in Fig. 4, thereby rocking the shafts in the other direction and moving the cams 22 out of operation and causing the cams 23 to act to raise the other side of the die-support to shift the die to the position shown in Fig. 3, thus bringing its other edge into position to coact with the roller. The die will then remain in this position while the roller makes the return stroke of its reciprocation.

In order that the leaf maybe readily placed in position on the cutting-die and properly smoothed out, it is desirable that the cutting edge of the die shall not extend above the surface of the table while the leaf is being placed in position. In order to secure this result, the yoke is provided beyond the shoulder 30 with a pocket 33, so positioned that the stud 29 may move beyond the shoulder 30 and will by such movement move the yoke into an intermediate position, in which the rock-shafts l7 and 18 and the cams 22 and will be in the positions shown in Fig. 1, in which the lugs 16, extending from both sides of the die-support, are allowed to rest on the rock-shafts. The die will then be in the position shown in Fig. 1, with its cutting edge substantially flush with the surface of the table. At the beginning of the movement of the arm 13 from this position the stud 29 will, by engagement with the shoulder 30, throw the yoke to bring the cutting-die into the-position shown in Fig. 3 before the roller 12 reaches the end of the die.

An adjustable stop 35 is preferably provided in the yoke 26 for limiting the movement of the arm 13, and by forming the face of the elevated portion of the cams 23 slightly eccentric, as shown, this adjusting-screw 35 provides means for adjusting the amount of elevation given to the die by these cams. The surface of the elevated portion of both the cams 22 and 23 should, however, be near enough concentric with the axes of the shafts 17 and 18 so that when the cams have been shifted to raise one side of the die-support the pressure of the studs 21 on the cams will not tend to throw the cams again, and thereby permit the support to drop.

As usual in machines of this kind, a perforated platen 36 may be provided inside the cutting edges of the die, yieldingly supported bysprings and limited in its upward movement by nuts on rods, as shown, and the space beneath the platen 36 may be connected with suitable exhausting apparatus through the opening 37.

It will be seen that by the construction shown, in which the die-support is supported at points beyond the limits of the die when one edge of the die-support is raised, the die will not only be tilted, so as to raise opposite sides thereof alternately, but will be raised bodily, so as to secure a substantial projection of the cutting edges of the die above the surface of the table without the necessity of too great a tiltingthereof, and so that the cutting edge near the ends of the die will be sure to be in position for coaction with the roller.

It will be understood that the invention is not to be limited to the exact construction and arrangements shown and to which the foregoing description has been mainly confined, but that it includes changes and modifications therein within the claims. It will be understood also that while the invention has been made especially with the idea of providing an improved mechanism forcutting wrappers or binders for cigars, yet the invention or features thereof may be found useful and may be employed for other purposes.
